Claims.

This invention relates to an operator for a storm sash and a window sash, and more particularly to an operator controllable from the interior of the building to which the sashes are attached.

An object of my invention is to provide convenient means controllable from the interior of a building, whereby a storm sash can be opened or closed without the necessity of first opening a Window sash to gain access to operating mechanism.

Another object of my invention is to provide operating means of the class described in which the degree of opening is adjustable to various intermediate positions, ranging from the closed po-' sition to the position representing the maximum opening provided.

,A further object is to provide a sash operator in which means is includedfor raising and lowering the upper window sash simultaneously with the closing and opening of the storm sash by the operation of a single common control member.

To these ends, generally stated, the invention consists in .the novel parts and novel combinations of parts hereinafter defined in the. claims and described in the following specification, made in connection with the accompanying drawing, wherein like reference characters refer to the same or similar parts throughout the various Views, and, in which,

. Fig. l is a vertical sectional view taken through a window frame structure and illustrating an embodimentci the invention operatively applied for use, certain of the movable parts being illustrated in one position in full lines-and in another position in dotted lines; e

. Fig, 2 is a horizontal sectional View taken on the line 2-2 of Fig. l, as indicated by the arrows;

3 is a verticalsectional View taken on the line 3-.3 of Fig. 2, as indicated by the arrows; Fig. 4 is a vertical sectionallview taken on the line is- 1 of Fig. l, as indicated by the arrows; and

Fig. 5 is a vertical sectional viewtaken on the line '5-5 of Fig. 2, as indicated by the arrows. .Beferring to the drawing io. a wall W, the exterior surface of which is indicated by W a and the :interior surface of which is indicated by Wb, a window sash frame 6 ,of conventional form is mounted. In the window sash frame 6, an upper window sash 7 and a lower window sash 3 of conventional form are slidably mounted to permit vertical motion with respect to the sashirame. Outward of the window-sashes '7 and-8 is a storm sash 9 pivotally connected at its lower end to sill 1932. Serial No. 589,850

1110f sash frame 6 by means of hinges 11. The

storm sash may be swung from a closed position shown in full lines Fig. .1 to an open position beyond the upper end of the storm sash, is at tached to the outer surface of the storm sash. A pair of bars 13 are pivot-ally and removably attached to a lug 14 on the inner face of said plate '12 as by means of a cotter pin 13a running through short vertical slots in the outer ends of the bars 13. The said bars 13 extend in a substantially horizontal direction through a channel-shaped casing in line with apertures 15 in the sash frame 6 to a point beyond the inside surface of the upper portion ofthewindow sash frame. The plate 12 is of such size and proportion as to ei'lectively cover aperture 15 at the outer side of the sash frame 6 when the storm sash 9 is in the closed position. On the underside of each of the two bars 13 are formed rack teeth 16. The inner end of the bars are pivotallyattached to an operating lever 17 of arcuate shape, said operating lever having a projecting straight handle portion 17a. The upper end of the operating lever is formed into a ball 18, said ball being retained in pivotal and vertically slidable relation within a vertically disposed guide 19 of C-shape in horizontal cross section, said guide being attached to the interiorv Iace'Wb of the wall W above the window sash framev 6. 1 An upturned lip 21 of the casing substantially flush with the inner face of the upper member of the Window sash frame 6 is adapted to be engaged with-the rack teeth 16 of the bars 13. Disposed .within the casing 20' is a gear rotatably mounted on a pin 23, said pin lying in a plane parallel to the plane of the sash frame 6 and supported at its ends by the side walls of the casing 20.-The gear 22 is engaged with the rack teeth 16' of the bars 13. Above the bars 13 is a pin 24, said pin being supported at its end-sby the side walls of the casing 20 and located a suitable distance above the pin 23 to permit a slight upward motion of the bars 13 sufficientto allow disengagement of the rack teeth 16 from the upturned lip 21 0f the casing 20 without allowing 1 the rack teeth 16 to be disengaged from the teeth of the gear 22. A vertically disposed racks?) with inwardly-projecting teeth 26 is pivotally attached,

as by a pin 27a, at its lower endto a lug 27 which is secured to the upper member of the upper window sash frame '7. The rack is so located that it passes between the two bars 13. The teeth'25 of the rack 25 is engaged with'the. teeth of the An, outwardly and downwardly sloping rain shield 29 is attached to the outward surface Wa of the wall W above the window sash frame 6.

Operation Assuming the storm sash 9 to be in closed position indicated by full lines Fig. 1, the operation to open the storm sash to the dotted line position is as follows:

The handle portion 17a of the operating lever 1'7 is slightly raised to disengage the rack teeth 16 of the bars 13 from the upturned lip 21 of the housing 20. The operating lever 17a is then pushed toward the sash frame 6, thus pushing the upper end of the storm sash 9 outward to the dotted line position Fig. 1. As the operating lever handle 17a is pushed outwardly, the ball-shaped end 18 of the operating lever 17 moves upward in the guide 19.

Referring to Fig. 3, as the above described operation is performed, the bars 13 are moved in an outward direction. Since the teeth 16 of the bars 13 are engaged with the teeth of the gear 22, outward motion of the bars 13 will cause clockwise rotation of the gear 22. Since the teeth of the gear 22 are engaged with the teeth 26 of the rack 25, clockwise rotation of the gear 22 will cause downward motion of the rack 25. The rack 25 is attached to the upper window sash '7 and hence the downward motion of the rack 25 results in downward motion or opening of the window sash '7.

To close the storm sash 9 and raise the upper window sash 7, the operation consists of slightly raising the handle 17a of the operating lever 17 and pulling the handle inward. The'operation of the various parts of the structure are obviously in the direction opposite to that described in connection with the operation of opening the storm sash.

The bars 13 can be disengaged from the lug 14 by removing cotter pin 13a when it is desired to remove the storm sash 9 for summer storage. The vertical rack 25 can be disengaged from the lug 2'7 by removing pin Z'Ia'if it is desired to operate the upper window sash 7 independently of the operator while the storm sash is in summer storage.

It will be seen that the operator is simple in construction and in'operation. It will also be observed that if the lip 21 is eliminated, the storm sash 9 can be readily swung to and from open position merely by operation of the sliding sash 7. The rain shield 29, of course, prevents rain or snow from falling between the storm sash 9 and the lower sliding sash; Although the operator is particularly applicable for use at the top of a window sash frame for opening and closing a storm sash hinged at its lower edge to the sill of the window frame, it will be understood that the operator by slight changes in the construction thereof, could be adapted for use adjacent the bottom of a sash frame for controllinga storm sash pivotally mounted onthe sash frame at its upper edge.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various parts without departing from the scope of the present invention.

What is claimed is:

l. The combination with a window sash frame and a swinging storm sash, of a storm sash operator comprising a bar pivotally connected to the swinging edge of the storm sash and extending inwardly through the sash frame, a lever pivoted to the inner end of said bar and a guide mounted at the inner side of the sash frame within which said lever is pivotally and slidably mounted.
